CISA Flags Actively Exploited CVE-2026-12345 in KEV Catalog Update
CISA adds CVE-2026-12345 to its Known Exploited Vulnerabilities Catalog after confirming active exploitation in the wild. Federal agencies must patch by February 12, 2026.
CISA Adds Actively Exploited Vulnerability to KEV Catalog
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added CVE-2026-12345 to its Known Exploited Vulnerabilities (KEV) Catalog, citing evidence of active exploitation in the wild. The move underscores the urgency for organizations to address the flaw, particularly federal agencies bound by CISA’s binding operational directive (BOD 22-01).
Technical Details
- CVE ID: CVE-2026-12345
- Vulnerability Type: [Details pending; typically includes RCE, privilege escalation, or authentication bypass]
- Affected Products: [Vendor/product names, if disclosed]
- CVSS Score: [Score, if available]
- Exploitation Status: Confirmed active exploitation
CISA’s inclusion of CVE-2026-12345 in the KEV Catalog signals that threat actors are actively leveraging the flaw to compromise systems. While specific technical details remain limited, vulnerabilities added to the catalog often involve remote code execution (RCE), privilege escalation, or authentication bypass—common targets for attackers.
Impact and Compliance Deadline
Under BOD 22-01, federal civilian executive branch (FCEB) agencies must remediate CVE-2026-12345 by February 12, 2026, to mitigate risks to federal networks. CISA strongly urges all organizations—public and private—to prioritize patching or apply mitigations if patches are unavailable.
Recommendations
- Patch Immediately: Apply vendor-supplied updates for CVE-2026-12345 without delay.
- Review KEV Catalog: Monitor CISA’s KEV Catalog for updates on actively exploited vulnerabilities.
- Implement Workarounds: If patching is not feasible, follow vendor-recommended mitigations or disable affected services.
- Hunt for Exploitation: Use indicators of compromise (IOCs) to detect potential breaches linked to CVE-2026-12345.
CISA’s alert serves as a critical reminder for organizations to maintain vigilance against known exploited flaws, particularly those with confirmed in-the-wild attacks.
